SNAP FASTENER.

Application ,led August 29, 1.9521. -Serafol 496,543.

To all 'whom it may concern.' y

Be it known that l, EMIL AUGUST BAIL, a subject of the Republic of Saxony, German lt'epublicfand a resident of Lausa, near Dresden, Republic of Saxony, German Republic, have invented new and useful lmprovernents in Snap Fasteners, of which the following is a specification.

mrlhe invention relates to garment fastening devices generally of the type known as snap fasteners and consisting. as a rule of interlocking male and Lfemale members, the male element being ordinarily provided lwith a rounded projection or ball which ts within a correspondingly shaped socket in theA female member. rlFhe nature of the improvement resides in the provision of anaperture centrally7 located in the ball of the male part of the fastener and preferably also a corresponding aperture in the center of the fe'- male part of the fastener for the-purpose of enabling a needle or equivalent device to be passed through said apertures to center definitely the opposed member of. the fastener with respect to its correspondlng member.

lfn sewing on snap fasteners, a known drawback is that the place fixed in advance l for the stud and socket respectively of the snap fastener is rarely reached or ensured.

The consequence of this fact isthat the edgesv of the stuft' or cloth laid one above another are distorted or contracted, said distortion being caused by the mutual Wrong position of the parts of the snap fastener, whereby the stuff or cloth is stretched or strained. lt frequently happens that snap fasteners arranged in a wrong manner-injure the good fit` of a dress even though it loe-otherwise well finished.

'lwo reasons cause the difficulty to obtainv or ensuring the right iitor relative position of the stud and socket of the snap fasteners. (lne of these reasons is the possibility that the stud of the snap fastener does not occupy the place intended because the latter cannot be seen or located in spite of the socalled marking. The ordinary markingneedle fiat-inserted against the surface of the stuff or cloth can only generally mark or designate the place which vthe stud or socket of the snap fastener belongs to.`

rllhe second ofsaid reasons consists in the fact that a displacement of the parts of the ldisplacement is caused/by the fact that as the I'snap fastener is held by hand on the stuff or cloth, the needle is generally first. ypassed through one of the holes ofthe snap fastener which are situated near the outer edge ofthe latter. Consequently, the drawing of a thread into and through one of said holes is by no means suicient for the fiXation of 'the position of the studor socket of the fastener. As the fastener element must be released for the reason that the finger covers the other holes provided on the edge of the mentioned parts. Therefore, a passage of the needle through said holes without in any way changing the ,position of the finger is not possible. ln most cases therefore, said' fastener element-is, after being released, subject to an oscillating movement round that point as center on which it is-held by the thread-stitch, and thus displaces itself on the stuff or cloth surface and' assumes or takes therefore a wrong position,

whereby itis neither situated on the placeI lthe stu' or cloth are placed one above another.

. Now, the present invention has for its object to lprevent or remove the drawbacks mentioned above, in other words to obtain or ensurel a fully right fit of the two fastener elements in such a manner that the, latter are precisely placed on the point intended inadvance during the marking-procedure and, besides,this to render, a displacement of the fastener element on the stuff or cloth impossible during the sewing on operation.

Said advantagesy are obtained by providing a central opening Within the middlehead of 'the soc'ket and stud in such a malnner that a needle can be passed through each of the parts mentioned.

Whereas, during the` so-called markingllt will be evident without anyidiflculty that the place selected for the center of'thefastener cannot be markedin any more precise manner than by a needle vertically passed through the stuff or cloth. Now, therefore, the arrangement of a central opening in each part of the fastener allows the stud or socket to be easily placed on the neesured against any displacement. The needle can simultaneously be used or serve asa means or implement for sewing on the studl or socket of the fastener. Y

'llhe drawing annexed to the description represents the object of the present invenl description that the snap fastener comprises .adapted to be temporarily tion. Figs. l and 2 show the fastener in section and Figs. 3 and 4 in elevation.

' a is the socket and lb the stud of the fas- 4 tener. Both parts are of a well known arrangement and shape 'and are fastened on the edge d of the stuff' or cloth by holes c situated near .the periphery of the socket andstud." I

Now, according to the present invention, each of both fastener elements is provided with a central opening e arranged within the apex or upper extremity of the heads f of the parts mentioned. g are needles represented in Figs. 1 and 2 in dotted lines. They are' vertically passed through the stuff or cloth d in such a manner that the socket a and stud I) of the faste-ner are brought or placed into the vright position by sliding or putting the fastener elements onto said needles passed through the central openings e provided in the stud and socket of the fastener.

It will be observed from the foregoing a pair of co-operating members, each of ,which has a centralizing aperture, these apertures being adapted to coincide when the two snap fastener members or elements are larranged in co-operating position and that the needle or penetrating means is introduced through these apertures in the fastener elements when one of said elements has been arranged in a desired position to determine the proper location at .which its co-acting member or element mustbeheld during att'achment. The. fastener elements are, consequently. formed with corresponding, coinciding apertures for obtaining registry of the parts, the needle being adapted to be introduced through said apertures for the purposes described. The location of the aperture in the stud member is preferably 'the terminus thereof, whereas the button which is constituted as the socket or female' element has a central aperture coinciding in area and position with that of the stud. rThe method of using the snap fasteners consists lgenerally in applying one element of I named element a needle which.A indicates on 2 the juxtaposed piece of cloth tlie proper centralized of the fastener is to be attached to said cloth. This second element is then finally stitched or otherwise fastened in the position indicated for it by the needle which centrally penetrates the element and thereby defines its position. Either the male member or the female member may be first stitched to one of the two pieces of cloth in a permanent manner before the central aperture thereof is used to indicate the position of the co-operating fastener element. lVhen the male member is the first one to'b'e thus permanently afiixed, the female member is then merely placed on the male4 member inl the same positionl in which the two elements function together in use, whereupon the second piece of cloth which is to carry the female member is brought to the proper position and the needle is' then passed through the two central openings of the two fastener osition at which the second element' elements and into the second piece of cloth at exactly the proper point at which the yfemale element is to be fastened permanently thereto. A female fastener element is then permanently sewed to the point thus indicated. When the first fastener element to be permanently attached to one of the pieces of cloth is the female element, the process is merely reversed.

Iv claim:

1. A snap fastener element comprising a flange centrally open and circumferentially apertured for attachment to cloth by means of stitching and a member centrally located with respect to said apertures and projecting out of the plane of said flange and shaped for co-operative'engagement with a cprresponding fastener element of opposed sex, said projecting member being provided at its centralpoint with an opening slightly larger in diameter than the thickness ofa needle, and a free passage adapted for penetration by a needle between said opening and the flange and entirely through said projecting member. V

2. A garment fastening device comprisi'ng a male and a female element, each having a flange centrally located with respect to said apertures andy projecting out of the lplane of said flange and Ashaped for co-opl opening slightly larger in diameter than the thickness of a needle, and a free passage incide when said members are arranged in co-operating position, of penetrating means adapted to be temporarily introduced through said apertures when oneV of the members has been arranged in a desired position to determine the proper location at which its coacting member must be held during attachment. I

4:. In means of the class described, the combination with cooperating elements, one of which -consists of a headed member and the other .a socket member adapted to receive said headed member, said members being formed with corresponding coinciding apertures for obtaining registry of the parts, of a penetrating member adapted to vbe introduced through said apertures when one of the members has been attached to determine the proper relative position of and hold the other member during fastening in place, each of said members being provided with openings to receive thev fastening means.

5. As a new article of manufacture, a snap fastener, consisting of co-operating memlbers comprising a. stud, the terminus of which is formed with a restricted aperture, and a button provided with asocket element to receive the stud andl with a central aperture in said socket element coinciding in area and position with the aperture of the stud.

6. In the art of dress making, the method of alining of the respective members of ball and socketfasteners which consists in applying to a piece of cloth one element of said fasteners in substantially the position which said element will retain when in use, laying against said element the piece of cloth which is to carry the other element of said fastener, and then introducing through the cen.l ter of the first named element a memberv adapted to engage lthe juxtaposed piece of cloth whereby to .indicate onv the latter the proper centralized position at which the second element of the ball and socket fas- -tener is to be attached to said cloth for proper centralization with respect to the first named element lpreliminary to being permanently applied tol the said juxtaposed piece of cloth..

7. In the art of dress making, the method of alining the respective members of ball and socket fasteners .which consists in applying j to a piece of cloth one element of said fasteners, introducing through a centralizing opening a member adapted to penetrate and thereby mark a piece of cloth which is to carry the other element of said fastener when said last named piece of cloth is juxtaposed with respect tothe first mentioned fastener element, thus denoting the lproper centralized position on the juxtaposedr piece of cloth at which the co-operatving member of the ball and socket fastener must be secured to obtain the proper relative cooperative Iposition of said ball and socket fastener members.

8, ln the art of dress making, the method of alining the respective members of ball and socket fasteners which consists first in applying permanently to a piece'. of clothpthe male member of such ball and socket fasten-l er, disposing the female member thereon in operative position, then juxtaposmg a secondspiece of cloth whichis to carry the female member permanently in `the position which said cloth will assume when the members ofthe fastener are properly secured together and to their respective pieces of cloth, then passing through centralizing openings formed in the male and female members, a I penetrating member whereby to engage the EMrL AUGUST Barri.
